OH man, i know this is an old post, but it is good to know others have this too! last night was horrible! the sweat, nausea, tachy, rushing to the toilet for soft BM.... almost feels like there is something bad inside me that my body is trying to get rid of... anyone feel like that? i feel i need to go to the ER to get IV fluids, but have no ins. or $ so i have to wait it out, and eat a whole sleeve of saltines and sip water... it continues for a while, repeating the BM and sweating nausea and tachy while my bf snores away loudly not caring... i do know he probably cares, just doesnt understand... and has to work EARLY so i cannot blame him... i just truly feel like dying when this happens it is so scary and frankly, it *****! finally i think it settled down maybe 45 to an hour, and i fell asleep, THANK GOD! any remedies or advice? i am going to look into the adrenal surges like many of you suggested in the past, and also the hyperaderengic thing sounds likely... although i wish i would have had the energy, to take my bp hr while happening... but could not think of doing it.... why do we all go through this and have no sympathy from the normal people in our lives.... it *****! if you havent experienced it, you have no idea!!! that is all i keep telling myself of my family for not being able to understand, or empathise... GRRRRRRRR!
